Shop Window Fan, recycled from Kitchen

I recently changed out the exhaust fan hood for my stove in the kitchen. While the paint had peeled on the hood and looked it age the fan motor was still in good shape. In taking it apart I saw how easy it would be to make a holder for it to mount to my window as you would an A/C unit. The fan is variable speed so I used a speed control switch rated for well over the 1/16th HP motor. Took apart the old filter elements for the fan and peeled off a single layer of the mesh to put on the intake side of the motor keeping fingers, bugs and cat paws from going inside.

The entire unit locks into the bottom lip of the window frame and the top lip of the window. To keep the window down I cut a piece of 2×4 to length and jammed it in place as a mechanical lock from the inside. This unit works amazingly well and replaces a cheap plastic one that pushed some air but nothing like this one can. This allows that side of the shop to push air into the larger shop. Inside the main side of the shop I have a exhaust fan opposite from this fan that pulls the air out.

Wasn’t really looking for A/C cold air, I have a A/C unit if I wanted to be that cold. Just a fan that gives me some airflow but not blowing the sawdust all around in my face while doing so. Using the window frees up floor space I had used for a pedestal fan for many years. Considering the price of free for the motor I call this a win.
